Abstract
Description
Technical Field
[0001] This utility model relates to the field of stapler technology, specifically to a stapler suitable for staples of different sizes. Background Technology
[0002] A stapler is a device used to bind paper items together. Staplers are widely used in offices and other fields.
[0003] A stapler typically consists of a base, a pressure handle, staple slots, a staple pusher, a pusher mechanism, and a spring system. The pressure handle is connected to the base via a pivot and converts hand pressure into downward thrust. The staple slots are rotatably mounted on the base, are generally elongated, and store staples; the front end of the slot has a staple outlet. The pusher mechanism is slidably mounted within the staple slot and, under the action of the spring system, pushes the staple forward. The staple pusher is fixed to the front end of the pressure handle and, when pressed down, pushes the staple out of the staple outlet and through the paper. The front end of the stapler's base has a groove where the staple bends and closes after penetrating the paper. When a staple needs to be inserted, the pressure handle is pulled up, and the pusher mechanism retracts under the action of the spring system. After inserting the staple, the pressure handle is lowered, and the pusher mechanism, under the action of the spring system, pushes the staple forward and presses it against the front end of the staple slot.
[0004] Existing staples come in various sizes, such as "24 / 6, 26 / 6, 23 / 8, 23 / 10", etc. Different sizes of staples are often needed when binding different sizes of paper. However, existing staplers are only compatible with one size of staple. Using different sizes of staples can lead to assembly difficulties and staple jamming. This means that the stapler needs to be replaced when different sizes of staples are required, which is not only inefficient, but also involves economic expenditure when purchasing multiple staplers, thus increasing costs. Utility Model Content
[0005] This application provides a stapler suitable for staples of different sizes, which solves the technical problem that staplers cannot adapt to staples of different widths.
[0006] This application provides a stapler suitable for staples of different sizes, comprising: a staple groove for accommodating staple material, a first plate disposed in the staple groove, a second plate disposed in the staple groove, and a spring assembly for clamping the staple material between the first plate and the second plate; the first plate and the second plate both extend along the length direction of the staple groove, and both can slide along the short axis direction of the staple groove.
[0007] By adopting the above technical solution, a sliding first plate and a second plate are set in the staple groove, and the first plate and the second plate are clamped on both sides of the staple material by a spring assembly, so that the equipment can be adapted to staple materials of different widths and sizes, thus improving the practicality of the equipment.
[0008] Preferably, the bottom of the staple groove is provided with a first groove that penetrates the staple groove housing along the short axis of the staple groove. A rotatable screw is provided in the first groove, and the screw extends along the length of the first groove. The screw includes a first section with a positive thread and a second section with a negative thread. A first connecting part is provided on the first plate and threadedly connected to the first section. A second connecting part is provided on the second plate and threadedly connected to the second section. The length of the first spring in its natural state is less than the width of the staple material.
[0009] By adopting the above technical solution, a first section with a positive thread in the opposite direction and a second section with a negative thread in the opposite direction are set on the screw, and the first plate and the second plate are threadedly connected to the first section and the second section respectively, so as to realize the synchronous back-to-back movement or synchronous front-to-back movement of the first plate and the second plate, and complete the synchronous control of the first plate and the second plate.
[0010] Preferably, the two ends of the screw are respectively located at the two ends of the first groove, and each end of the first groove is provided with a bearing. The screw is rotatably connected to the first groove through the two bearings.
[0011] By adopting the above technical solution, and by setting a bearing at the connection between the first groove and the screw, the frictional resistance during screw rotation is reduced, and the smoothness of screw rotation is improved.
